Question

It takes 50.0 J to raise the temperature of an 8.20 g piece of unknown metal from 13.0∘C to 24.2 ∘C. What is the specific heat for the metal

Answer 1

`c=0.544\ J/g^(\circ) C`

Step-by-step explanation:

Given that,

Heat required, Q = 50 J

Mass of unknown metal, m = 8.2 g

The temperature rises from 13.0°C to 24.2 °C.

We need to find the specific heat for the metal. We know that the heat required to raise the temperature is given by :

`Q=mc\Delta T`

c is specific heat of the metal

`c=(Q)/(m\Delta T)\\\\c=(50\ J)/(8.2\ g* (24.2-12)^(\circ) C)\\\\c=0.544\ J/g^(\circ) C`

So, the specific heat of the metal is
`0.544\ J/g^(\circ) C`
